Popis:	Lithylated bis(trimethylsilyl)hydrazines, Li2N2(SiMe3)2 and LiH N2(SiMe3)2 react with (Me3Si)2NECI2 (E ˭ P or As) to form hetero atom incorporated tetrazenes, 1,3.4,4-tetrakis(trimethyIsilyl)-2-phospha-I-tetrazene (Me3Si)2N‒ N(SiMe3)‒ P˭NSiMe3 and 1,1,4,4-tetrakis-(trimethylsilyl)-2-arsa-2-tetrazene (Me3Si)2N‒N˭As‒N(SiMe3)2. The former thermolyses primarily into trisila-phosphatriazene (Me3Si)2N‒P˭NSiMe3 and tetrasilahydrazine (Me3Si)4N2, whereas, the latter forms tris(trimethylsily1)hydrazine (Me3Si)3N2H. Phosphatetrazene interacts with CH3OH in an oxida-tive addition reaction to form [tris(trimethylsilyl)-hydrazino]-(trimethylsilylimino)-(methoxy)-phosphorane, (Me3Si)2N‒N(SiMe3)‒PH(OCH,)(˭NSiMe3), whereas, arsatetrazene undergoes cleavage reaction to yield (Me3Si)3N2H.
